Hi All,

It was since a few month that I had Question, but now i have one again.
Please if you can, help me.

Problem: I read the bcd value from the RTC and would store in a defined
program memry location. The content of this location will be displayed by the LCD routin.It is a common LCD routin, I use this method to display other fix strings,so i dont want to change the method,if it is not necessary.

The sample code is:
TIMER_HOUR:
DB 8Bh;position addr. of LCD
*DB '1'
DB '4'
TIMER_MIN:
DB 8Eh;position addr. of LCD
DB '31'
DB 000h ;end of the string char
----------------------
Question is: how can I modify the content of *-sign(e.g. adress is 04h) location from the main program.

I tried the following
MOV R0,#04h;
MOV @R0,#'2';

But it is not working. It run without any error:) and result:(
The LCD displayer routin display 1. The LCD routin is working fine,because if I modify the number at * localy, it display the modified value.

Thanks for Your answere,
Peter
